High-volume 120 mm server fan

The Zyvpee V34809-90 is a 120 mm by 38 mm axial-flow fan built for server chassis and high-density cases. It targets builders who need concentrated airflow through restrictive layouts such as dense drive cages or radiator stacks. The 4-pin PWM connector allows motherboard speed control. It is not suited for silent desktop builds where low noise is the priority.

3.3 A DC 12 V power envelope

The fan draws 3.3 A at 12 V, so the 4-pin header or fan controller must supply that current continuously. Headers rated for lower amperage can overheat or shut down under sustained load. The 4-wire design provides tachometer feedback and PWM control, but voltage regulation is fixed at 12 V DC. Builders using adapters or splitters should verify the combined draw stays within the header limit.

3000 to 3499 RPM with over 80 CFM

The speed range of 3000 to 3499 RPM delivers more than 80 CFM of airflow through the 38 mm thick frame. Ball-bearing construction supports continuous operation at these speeds. This specification determines whether the fan can meet the thermal demands of a given server or workstation configuration.

Questions about this item

Should I pick the 3000-3499 RPM version for maximum airflow?

The fan runs at 3000-3499 RPM and moves more than 80 CFM, so this single version already delivers the high-volume output quoted for server cooling.

What does the >80 CFM rating mean once the fan is installed in a case?

It indicates the fan can push over 80 cubic feet of air per minute through an unrestricted path; actual flow inside a chassis will be lower due to grilles, filters and component obstructions.

How does the 4-pin connector control speed and what limits it?

The 4-wire 4-pin plug carries 12 V at up to 3.3 A and provides a PWM signal for variable speed control, with the fan's own 3000-3499 RPM range as the upper limit.
